Can someone pls me find the lowest common denominator of

x³y⁴

The Lowest Common Denominator of fractions is the Least Common Multiple of their denominators. That is, you want to find the LCM of ...

Find the highest power of each of the factors, and multiply those together.

The highest power of x is x³. The highest power of y is y⁴. So, the LCM of these expressions is ...

... x³y⁴

Then the two fractions are ...

... 3y³/(x³y⁴) . . . and . . . 7x²/(x³y⁴)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
